C) the production of CO2 by respiration. D) the burning of vast amounts of rain forests. E) none of the above 2) Which of the below statements about global warming is FALSE? A) Greenhouse gases allow sunlight to reach and heat the earth. B) Greenhouse gases prevent heat from leaving the earth.
This effect is caused mostly by the lack of vegetation and soil moisture in urban areas, which would normally use the absorbed sunlight to evaporate water as part of photosynthesis, which is known as a process is called evaportranspiration. Because urbanized land areas cover only a very small fraction of the Earth, the effect of the urban heat island on global average temperatures is very small. Most thermometers are located in urbanized areas; those areas tend to become more urbanized over time. Many buildings found in urban areas have dark surfaces. Dark surfaces absorb more light energy, and heat, making the entire building warmer.
These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
It increases as the Earth’s atmosphere warms which makes it the most feedback mechanisms to the green house effect. Carbon Dioxide is released through natural activities like volcano eruptions and human activities like deforestation and burning of fossil fuels. We have seen that humans have increased their atmospheric CO2 concentration by a third since the Industrial Revolution. Methane is a hydrocarbon gas, which is produced through natural sources and human activities such as decomposition of wastes in landfills and rice cultivation. Methane is a more active green house gas than CO2 but is less abundant in the atmosphere.
limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
However seasoned wood should burn quickly because of its relative dryness. I found that white oak has an excelent rating for burning. It has a high heat yeild and the burn difficulty is easy. It is hard to split. It produces light smoke and no sparks.
| | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period. | Greenhouse Effect | The greenhouse effect is caused by atmospheric CO2 but is necessary to keep the surface of the Earth at a habitable temperature. | | Increased levels of atmospheric CO2 could cause global warming and significant climatic change. | | Life on Earth is protected from dangerous radiation by a protective layer or ozone molecules present in the atmosphere.
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
We then, can assume the reason for the increasing temperature was resulted from industries, over-powering energy with coal during that specified time period. Manufacturing produces massive amounts of carbon dioxide along with other greenhouse gases, resulting in warming the whole planet, hene causes climate changes. Thus, it can be concluded that humans have a strong correlation with the increasing temperature and climate changes that are happening
